Ok, maybe Quickbird then. quote: Orbit Altitude: 450km - 98 degree, sun-synchronous inclination Revisit frequency: 1 to 3.5 days depending on latitude at 70-cm resolution Viewing angle: Agile spacecraft, in-track and cross-track pointing Period 93.4 minutes
So I'll have whichever length of time means I'm still in the game!!

I know Also-Ran Tom Day already entered this one, but when I found it, I found the orbital period to be different than what he'd recorded.
So on that basis, I choose Envisat with an orbital period of 101 minutes.
(What an obscure question... )

Ahem. My lack of technical know how, and failure to understand anything in physics beyond the age of 14 has led me to make a small error. Ahem.
As shown by this website shamefaced-admittance-of-error.com, apparently the landsat5 takes just 99 minutes to orbit the earth, and the figure of 16 days is how long it takes to cover the entire earth. Thankyou for your patience, normal service will be resumed shortly.

currently (and not counting any of Tom's suggestions as actual answers), the current average is 2752 minutes (45.8 hours, just under 2 days) so currently in danger is Chandra [ 01. October 2005, 17:22: Message edited by: Papa Smurf ]

That'll be the "period" then - 93.4 minutes. The revisit frequency is how soon it looks at the same place on the planet.

To one aged smurf. You may wish to ask one of the ships physicists but I believe to "circumnavigate" the earth would mean to go around the earth relative to the earth. Otherwise we would all be orbiting the earth right now racing at the speed of over 1,000 mph. My I am faster than I thought.

AND - Unless my maths fails me, a geostationary satellite takes an infinite amount of time to circumnavigate, which when all is added up and divided by a finite number creates an average of approximately infinity.
This should surely result in a high originality factor, but elimination from the contest.
Or is my analysis wrong?

Earthbound geostationary satellites orbit the Earth. If they didn't, they would fall to the ground. Whether or not they 'circumnavigate' is beside the point.
From the Moon, the Earth remains stationary relative to the observer, it doesn't rise or set against the horizon. Does that mean the Moon isn't a satellite of Earth?

One of the Ship's physicists here, though not exactly unbiased. Though I guess the chances of me being knocked out this round are very small, for reasons discussed above.
quote: Originally posted by Quizmaster: 2) The time taken for your choice to complete one circumnavigation.
"Circumnavigation" means "to go round" from the Latin "circum" - around and "navigare" - to navigate.
It's actually a problem of relativity here!
The conventional approach is to say that the Earth is spinning and that it is orbiting round the Sun. If this is the case, then geostationary satellites are orbiting the Earth once every 24 hours, even though they stay above the same point on the surface. So at some times they are on the Sun side of the Earth (day) and at some times they are on the other side of Earth (night).
When talking about events happening only on the Earth, it is sometimes convenient to speak as if the Earth were stationary. Hence "the sun rising", etc. It is in this sense that Magellan's expedition "circumnavigated" the Earth. However, if we keep this view when we think about space, geostationary satellites would be held in place by the balance between "centrifugal force" and gravity. In this case also, pretty much everything in the universe could be said to be circumnavigating Earth, taking 24 hours to do so (though in the case of the Sun, Moon, etc with wobbles every 365.24 or 28 days).
The reason that the first approach is to be preferred is these "centrifugal forces", and also the Coriolis force. If we treat the Earth as stationary, we need to add them in as unexplained forces acting on everything and they make any calculations really horrible. If we say that the Earth is moving, we don't.
Incidentally, the reason satellites orbit is due to a combination of their speeds and gravity. If they weren't moving, they would plummet to Earth. If there wasn't any gravity, they'd keep moving in a straight line at a constant speed and fly off into space.
So my conclusion is that it could be argued that geostationary satellites do "circumnavigate the Earth" in that they go round it, even though they remain above the same point on the surface.
On the other hand, it doesn't matter as it's the geostationary ones who come close to the average whether they are counted as 24 hour orbits or infinite time. [ 02. October 2005, 06:45: Message edited by: Custard. ]

Right. so Tom's first entry was quickbird. he said it had a period of 1 day. THen pants also chose quickbird, and the info she posted showed it t have a period of 93.4 minutes.
does that mean that Tom's first, valid entry is
Aqua - period 99 mins ? In which case, Marvin's first valid entry would be the Radarsat 1. (100.7 minutes)
If so, (and using my 24hr geostationary assumpition/suggestion from earlier), the average is closest to GMS Hinari 1
mind you, if Pure As the Yellow Driven Snow declines to post this round then it all becomes immaterial.

To put it not-so-simply, we assume so.
Quiz Master says it is in Page 5, Paragraph 7, Section A, Subsection IX.
Perhaps Subsection X should outline whether or not averages will be affected by the Also-Rans' entries.

There has been so much rule bending this time around that I shall wait and see before the next round tonight whether Pure as Snow has found an internet cafe or is completely cut off from civilisation before I post my entry.
Rule) First ENTRY counts unless it is proven invalid, only then can you pick another satellite.
Rule) Also-Rans may post but only their first entry counts and it is then denied to competitors.
Rule) All valid entries count (Competitors and Also-Rans) when it comes to the averages.
Rule) Breaking the rules and getting away with it is part of the fun but can lead to disqualification.
Rule) A piece of wood or plastic 12 inches long.

ROUND NINE: DIFFERENT FLAGS
The FLAG round proved extremely popular in a previous quiz so this time I want you to choose a flag representing a country, a state, an area or a region. You must post a link to a website with a picture of your chosen flag.
Your flag must be different from all the other flags chosen. We will use colour, shape, number of colours, number of shapes, horizontal, vertical, images and match each flag with all the others. The person choosing the flag with the most similarities will be eliminated.
Good luck and make your flag as unusual as possible.
